My intraocular lens has moved out of position. How can it be treated?

When an IOL moves out of its normal position, vision may become blurry or objects may appear doubled. Treatment may involve repositioning or exchanging the lens. If there is insufficient tissue to support it, scleral fixation may be considered. The appropriate technique depends on the condition of the IOL and the structures inside the eye.

Does retinal detachment need to be operated on urgently?

Retinal detachment is an eye emergency, and the timing of surgery can have a major impact on vision after treatment. Prompt surgery is particularly important before the macula, the part of the retina ...

What is the difference between air and gas used during retinal detachment surgery?

During retinal detachment surgery, air or a medical gas may be placed inside the eye to help keep the retina in position while it heals. Air is absorbed faster than longer-acting gases, which can allo...

Will I have to lie face down after retinal detachment surgery?

Not always. Your postoperative positioning depends on the location of the retinal breaks, whether air, gas, or silicone oil was used, and the surgical technique. Some patients need to keep their head ...

Can retinal detachment happen again after surgery?

Yes. Retinal detachment can recur because of a new retinal break, remaining traction, or proliferative vitreoretinopathy, among other causes. Keep your scheduled retinal follow-up appointments, and se...

How long should I stop wearing contact lenses before my preoperative examination?

For accurate measurements, we generally recommend stopping contact lens wear for at least one week before the examination. Contact lenses can temporarily alter corneal shape and tear-film quality, aff...

I had LASIK or LASEK years ago, but my vision has become blurry again. Can I have another procedure?

A second procedure may be possible, but the first step is to identify why your vision has changed. Treatment will differ depending on whether the cause is residual nearsightedness or astigmatism, dry ...

Is enhancement surgery possible after SMILE?

Some patients may be candidates for further vision correction after SMILE. We first assess the depth of the original treatment, remaining corneal tissue, corneal shape, current refractive error, and t...

What is the difference between monofocal and multifocal intraocular lenses?

A monofocal intraocular lens is generally designed to focus at one distance. Multifocal lenses are designed to reduce reliance on glasses at multiple distances. However, some multifocal IOLs can cause...

When does an intraocular lens need to be exchanged?

IOL exchange may be considered if a lens becomes dislocated, if its power is significantly different from what the eye needs, or if substantial lens-related symptoms persist despite treatment of other...

What is scleral fixation of an intraocular lens?

Scleral fixation is a procedure used when an IOL cannot be supported reliably in its normal position. The lens haptics are secured to the sclera, the white outer wall of the eye. The Yamane technique ...

If I have a retinal problem, does that mean I need surgery?

Not always. Conditions such as epiretinal membrane, macular hole, retinal detachment, and vitreous hemorrhage require different approaches depending on their type and severity. Some can be monitored o...
